Does seafloor spreading hold the plates in place?
No, seafloor spreading does not hold the plates in place. Seafloor spreading is a process that occurs at mid-ocean ridges where new oceanic crust is formed and spreads apart. It is driven by the movement of tectonic plates, which are actually responsible for holding the seafloor in place.
Why is the crust broken into plates?
These plates move around slowly and bump into each other creating mountains, new seafloor, and earthquakes.
What is the zones places where the seafloor is forced under continents to drift?
These zones are known as subduction zones where tectonic plates collide, forcing one plate to be pushed beneath the other. This process leads to the formation of deep ocean trenches and can result in earthquakes, volcanic activity, and the creation of mountain ranges.
What Is the mechanism responsible for producing the new seafloor between two diverging plates?
The mechanism responsible for producing new seafloor between two diverging plates is seafloor spreading. Magma rises from the mantle to fill the gap created by the plates moving apart, solidifies upon contact with seawater, and forms new oceanic crust. This process results in the continuous growth of the ocean floor.
What is it called when two ocean plates move apart and new crust is formed?
Seafloor spreading
The collision of two tectonic plates produces a volcano what types of plates could be involved?
two seafloor plates and a seafloor plate and continental plate

Where the seafloor is forced under continental plates?
the subduction zone
What plates are causing seafloor spreading?
The plates causing seafloor spreading are known as divergent plates. These plates move away from each other, allowing magma from the mantle to rise up and create new oceanic crust at mid-ocean ridges. An example of such a plate boundary is the Mid-Atlantic Ridge.
Why Seafloor spreading is occurring at the boundary between the?
Seafloor spreading occurs at the boundary between tectonic plates because of the divergent movement of these plates. As the plates move apart, magma rises from the mantle to fill the gap, solidifying as it cools and creating new seafloor. This process is instrumental in the formation of mid-ocean ridges and plays a key role in the theory of plate tectonics.
How deep trenches are formed?
Deep-ocean trenches are formed where seafloor tectonic plates subduct under continental plates.
How does the process of seafloor spreading occur with two tectonic plates moving away from each other?
Seafloor spreading happens when two tectonic plates move apart. Magma rises up from the mantle through the gap, creating new oceanic crust. As the plates continue to move apart, the new crust pushes the older crust away, causing the seafloor to spread.
Are plates any where else but under the sea?
Yes. All of Earth's crust, both on land and on the seafloor, is composed of tectonic plates.
Why is the crust broken into plates?
These plates move around slowly and bump into each other creating mountains, new seafloor, and earthquakes.
What is the zones places where the seafloor is forced under continents to drift?
These zones are known as subduction zones where tectonic plates collide, forcing one plate to be pushed beneath the other. This process leads to the formation of deep ocean trenches and can result in earthquakes, volcanic activity, and the creation of mountain ranges.
Places where the seafloor is forced under continental plates?
The region where the seafloor is forced beneath the continental plate is called a subduction zone. When the seafloor descends down it produces a deep-ocean trench.
What is the driving force for seafloor spreading?
The driving force for seafloor spreading is the movement of tectonic plates. As magma rises from the mantle to the surface at mid-ocean ridges, it creates new oceanic crust which pushes the existing plates apart, causing seafloor spreading. This process is part of the larger theory of plate tectonics.
